WINDOW REGULATOR.

Application filed March 15, 1923. -Seria1 No. 625,291.

To all whom t may concern.'

Be it known that I, EMILFKOEB, a citizen of the United States, and alresident of Tuckahoe, in the county of Westchester and State of New York, have invented certain new -and useful Improvements in VVindowol Regulators, of which the following is a specification.`

M y invention relates towindow regulators l0 for raising and lowering windows and it is particularly adapted in its application to windows ot vehicles such as automobiles.

The principal object of the invention 4is the production of a window regulator of 15 simplicity of construction and ease of operation.

A vfurther object of the invention is the production of a window regulator having the above characteristics which Shall contain simple and effective means for holding the window against movement in either direction when power is applied thereto.

Further objects and advantages-will appear from the accompanying description, the invention consisting in the novel parts and combinations thereof hereinafter more particularly described and then Specilied in the claims...

In the accompanying drawing illustrating a practical embodiment of the invention:

Fig. 1 is a front elevation of a portion of a Window showing the'invention with parts so desired the lower portion of the window may be coveredbyupholstery 2l or any removed.

F1g.2 is a horizontal cross-section taken through thewindow.

Fig. 3 is a cross-section (partly'in elevation) of a part of the device.

Fig. 4 is a rear elevation of the part shownA in Fig.

Referring to the drawing: The side members ofawindow frame are indicated at 1,k these members .being provided with channels or guideways Q receiving and supporting a window which is slidable vertically therein. Said window 3 has a strip 4 secured in any desirable manner to the lower edge thereof, this strip being provided with a horizontal slot 5 therein.

A support 6 is secured to one of the side members 1 and is provided with upper and lower extensions 7 and 8 respectively. The

upper extensionhas a toothed` member 9 comprisinga gear pivoted theret While the terminates in a manual control member or 4andthe roller 12 which slides in slot 5' as lower' member has an operating arm l0 8. The function of said springs is to counterbalance the Weight of'the Window oF and to assist in the raising thereof.

An annular box or bearing 15 is fastened N to the extension 7, said boX- receiving and 0 supporting a rotatable hub member 16 provided with reduced members 17 and 18 whiclr extend through the wall of the extension' 7 andgthe vfront wall o'l"v the box' respectively as shown in Fig. The extension 17 terminates in a relatively-small pinion 19 shown in the present instance'as provided with three teeth. `This pinion meshes with the gear 9: The extension 18 shaft 29 receiving a handle or crank 20. It Will be noted that the radius of the pinion 19 is vz ippreciably smaller than the radius of' the hub member 16 and that the pinion is considerably smaller than the gear 9. It

`interpose spring washers 22 between the box 15 and the hub member 16 which act to `eliminate rattling and assist in the operation of the device.

To raise or lower the window the handle is rotated in the proper direction, the mo'y tion being transmitted through member 16, pinion'1'9, gear 9, gear 11, operating arm 10 has been explained. When the handle 'is released the window is automatically locked against movement when power is applied to the window itself because of the reduction gearing heretofore explained, together4 with the'fact that the comparatively large size of the hub member 16 as respects the pinion said springs being vsecured to thei extension 65 1.) provides a-large frictional surface for Contact with the box l which acts to resist such movement. In other Words the me chanieal disadvantage of the construction4 described produces a resistance lto a movement of the window too great to be jovercome byl power applied thereto, although the window is easily operated When power.

is applied to the driving member or handle.

` IVhat I claim as my invention is il; In a window regulator, an operating arm engagingthe Window, a handle, a hub yportion connected to said handle, a bear-- ing for said hub portion, a pinion connected to said hub portion and having -a radius appreciably smaller than the radius of said hub portion-and means engagingsaidpin- -ion and arm to permit movement of' the Window upon actuation of thefhandle.

2. In a Window regulator, an operating arm engaging thewindow, a`handle,-a hub portion connected to said handle, a bearing for said hub portion'and a pinionfconneetedto said hub .portion and having a radius' appreoiably smaller than the 'radius of said connected to said arm to permit movement fof the Window uponv actuation of said handle. '1 v.

3'. In a Window regulator, an operating .arm engaging the Window, a rotatable handle, a hub portion connected to said handle, va bearing for Vsaid hub portion, means connecting said hub portiony and said arm to -permit movement of the Window upon actuation of said handle and spring` means pressing against said hub portion in a di-l rection transverse to.- the aXls of rotation of said handle." y

,4. In a window regulator, an operating arm engaging the Window, a "handle, -a pinion, a gear connecting vsaid pinion. and said operating arm and connectin Lmeans, between said pinion and said han le,'said connecting means providinga frietionalA resisthe friction between said friction memberl .hub portion, said-pinion being operatively.,

tance to movement of the .Window when power is applied theretoand having a diameter appreciably greater than Vfthe diameterof said pinion.

5. Ina. Window regulator; a rotatable shaft, a member mounted for rotation with said shaft and provided with an enlarged.V

frictional contact surface, a fixed member having a cooperating frictional contact surface, means operated Iby said shaft and including a plurality of rotatable members for operating Said Window, a spacing member positioned for free movement 4bettve-en said member and said fixed member, and

means for' eounterbalancing the Weight of ing a thrust, Onsaid shaft which increases .and -said fixed member, and means for counterbalancing'the-Weight of said window.

7. In a 'Window regulator, a rotatable pinion, an enlarged lmember mounted for rotation with said inion and having a frictional contact surace of a diameter relatively larger than that of said pinion, a"

friction member havina ycontact 'surface cooperating With that o? said enlarged'member, a gear co-acting with saidpinion for operating said Window, and means for counterbalancing vthe Weight of said` win dow.

8.- In *a Window regulator, a window op 4erator including a rotatablehub member having an A'enlarged peripheral bearing surface, a manual control member connected to said hub member for rotating Vthe same and ber, manual control member and pinion being rigidly' secured lto one another ,for'simultaneous rotation,:a xed annular-bearing member encircling said hub member and provided with means for frictional engagement with the peripheral bearing surface' of said hub member, and Vmeans for moving said Windownpon rotation of said hub member, lsaid means includingy a gear meshing with said inion.'
